Inventor: EFANTIS ANTONIOS
IPC: H02H1/00
Filed: 1991-12-12
Abstract: A transformer ground fault protector is provided and includes sensing means to be positioned adjacent but spaced from the output of each secondary winding in a transformer having its secondary windings connected in series and at the midpoint of the series circuit to ground. The sensing means forms a capacitive circuit with the windings and generates an output voltage when the secondary windings are energized. The output voltages generated by the sensing means are combined which in normal operation of the transformer, results in a voltage having a magnitude substantially equal to zero volts. However, when a fault occurs in the transformer, the output voltages induced in the sensing means are unequal and opposite in polarity resulting in a voltage having an absolute value greater than zero when combined. The resultant voltage in turn is conveyed to a comparator which compares the magnitude of the resultant voltage with a predetermined threshold voltage. When the resultant voltage is greater than the predetermined threshold voltage, the comparator provides a positive output voltage which is used to bias a switch connected in series with the transformer primary winding to an open condition thereby to isolate the primary winding from its power supply. An LED is illuminated when the primary winding is isolated from the power supply to provide a visual indication of the transformer fault condition.

Title: Direct reduction process in rotary hearth furnace
Inventor: KOTRABA NORMAN L
IPC: C21B13/00
Filed: 1992-03-03
Abstract: The invented pellet reclamation process includes forming green pellets of a mixture of steel furnace dust, a carbonaceous material such as coal, charcoal, lignite, petroleum coke, or coke, and an organic binder. The green pellets are fed over a layer of burnt pellets on a rotary hearth furnace which successively conveys the pellets first through a drying and coking zone in which the pellets are dried and any volatile matter driven out of the carbonaceous material. The pellets then travel through a reduction zone where the pellets are subjected to a higher temperature at which the contained iron oxide is reduced and remains within the pellets and the zinc, lead and cadmium oxides are reduced, volatilized, re-oxidized and carried off as oxides in the waste gases. The reduced pellets (DRI) are ultimately carried into a discharge zone where they are discharged from the rotary hearth furnace. An apparatus for performing the process is also disclosed.

Patent CA-2064868-A1 (CA)
Title: Combustion apparatus
Inventor: MORITA SHIGEKI
IPC: F23D17/00
Filed: 1991-06-27
Abstract: A combustion apparatus comprises a mixture feeding pipe (1) through which a mixture of pulverized coal and combustion air flows. The mixture is injected into a furnace (2) through the mixture feeding pipe and then ignited. A radial outwardly flared flame maintaining ring (3) is provided at the tip end of the mixture feeding pipe. The flame maintaining ring is under a reduction atmosphere and exposed to high temperatures due to radiant heat from the furnace. Therefore, there is a possibility of burnout of the flame maintaining ring or growth of slag on the flame maintaining ring. In order to prevent this, a projection (6) is disposed to extend into the furnace beyond the flame maintaining ring so as to shut off radiation from the inside of the furnace to the flame maintaining ring adequately, thereby suppressing an excessive temperature rise. Combustion air flows along the surface of the projection so as to locate the projection under an oxidation atmosphere. A pulverized coal/air separating member (7) extends through within the mixture feeding pipe. A portion where separation of the flow is forcibly occurred is formed locally in a conical end portion (II) of the pulverized coal/air separating member. It is therefore possible to effect a combustion in a stabilized manner as a whole regardless of the unit capacity and load of the combustion apparatus. <IMAGE>

Patent CA-2080956-A1 (CA)
Inventor: BARLOW GEORGE J
IPC: G06F15/16
Filed: 1992-10-20
Abstract: A multiprocessor computer system having a first processor having a first interrupt mechanism for generating interrupt requests, a second processor having a second interrupt mechanism, and a system bus for communicating interrupt requests from the first processor to the second processor.  The second interrupt mechanism is responsive to an interrupt request by generating an acknowledge response on the system bus when the second processor accepts the interrupt request and generating a not acknowledge response on the system bus when the second processor contains a previous and pending interrupt request of higher level and refuses the interrupt request.  The second interrupt mechanism is responsive to the completion of servicing of an interrupt request by the second processor by placing on the system bus an interrupt completed command, which includes an address identifying the second processor and a code indicating that the second processor has completing servicing an interrupt request.  The first processor includes an interrupt retry means, which includes a refused interrupt register means responsive to a not acknowledge response from the second processor in response to an interrupt requested from the first processor for storing the channel number of the second processor, and level monitor logic connected from the system bus.  The level monitor logic detects the occurrence of an interrupt completed command on the system bus, compares the address in the interrupt completed command to a second processor identification stored in the refused interrupt register means, and generates a retry interrupt output to the first processor when the address in the interrupt completed command corresponds to a second processor identification stored in the refused interrupt register means. The first processor is responsive to an interrupt retry output from the level monitor means by retrying the corresponding previously refused interrupt request.

Patent CA-2081983-A1 (CA)
Inventor: KOZULIC BRANKO
IPC: G01N27/447
Filed: 1992-02-21
Abstract: The method of electrophoresis uses for separation of charged species their different mobilities in an electric field. The pro-cess is usually carried out by forcing the molecules to migrate through an aqueous gel. The gels are run in essentially two types of electrophoretic units: vertical and horizontal ones. It was found that in the standard submerged electrophoresis units the resolu-tion of DNA in the poly(NAT) gels was never so good as in the vertical system.  It was observed that by looking at the gel from above under an angle declined from the vertical, the viewed DNA bands in the gel were much sharper than they were pictured on the photograph taken by a camera positioned more or less vertically above to gel. On basis of this observation it was assumed that the diffuseness of bands seen on the photograph did not originate from a real diffuseness of bands in the gel, but rather from the vertical position of the camera and bending of the bands against the vertical axis. If the bands in the gel could be made essential-ly vertical, then the resolution taken by the usually positioned camera would be qualitatively better and besides that independent of the sample volume. It is the main goal to prevent such bending of bands in gels during electrophoresis.
